topic Always one value selected in App Development

Always one value selected

ali_hijazi — Mon, 23 Sep 2024 05:53:44 GMT

Hello
we've got an application in which we want 2 fields (currency, and aggregation_type) to be set to have always one value selected
we set this via the fields->settings

However we are using WIP as an archival tool for Qlik. Whenever we publish the app, this software empties the QVF from data so that it doesn't take too much space in the WIP database and so that publishing the QVF file executes fast.

but as you know when a QVF file is emptied from data, the always one value selected options will be lost
and we have to manually duplicate the app on teh server, re-set the option (alwasys one value selected) then publish and replace

is there a way to overcome this delimma

It should be possible to set this in a automated process using the Qlik Engine API: Qlik Engine - Field Description - AlwaysOneSelected.

I am not the correct person to explain how to do it, so if you don't then I suggest creating a new question under one of the more fitting forum topics.

Hello @Vegar
thank you for your reply
I managed through the engine API to set the always one value selected
but this had to be done by executing several Json codes
is there a way to put all the jason codes in "one" package and execute it by one click
